branchiostegal rays, and parts of the pelvic, dorsal, anal, 
and caudal fins. Lewis Coll. 
P. 9171. Another specimen deepened anteriorly hy distortion, 
showing the pectoral, dorsal, and caudal fins, and traces of 
the very fine serrations on some of the scales. The pectoral 
fin-rays are not less than 14 in number. Lewis Coll. 
47356. Specimen elongated by distortion, with remains of about 
40 vertebrae, and parts of the pelvic, dorsal, and caudal 
fins. Lewis Coll. 
Sardinioides pusillus, sp. nov. 
[Plate XVI. figs. 2, 3.] 
Type. Imperfect fish : British Museum. 
A small robust species, attaining a length of about 0*1. Length 
of head with opercular apparatus not exceeding the maximum 
depth of the trunk, which is contained somewhat less than twice in 
the length from the pectoral arch to the base of the caudal fin. 
Vertebrae 30 in number. Pins as in the type species, except that 
the dorsal comprises only 10 or 11 rays. Serrations of scales deep 
and conspicuous. 
Form. ^ Log. Upper Cretaceous : Sahel Alma, Mt. Lebanon, 
48123. The type specimen, shown of the natural size in PI. XVI. 
fig. 2. The open mouth displays very minute teeth, and 
its upper margin is clearl}’' formed by the slender ex¬ 
tended premaxilla. The maxilla, with its triangular 
distal expansion, is seen in imperfect impression above 
the premaxiUa. The stout parasphenoid marks the base 
of the cranium. The vertebrae are clearly not more than 
30 in number, and of these about 15 may be counted as 
caudal. The anterior abdominal region is much disturbed, 
and the paired fins are represented solely by an impression 
of the 6 rays of one of the pelvic pair. The dorsal fin 
comprises two comparatively short and slender spines, 
then the longest ray, articulated distally but not sub¬ 
divided, and then 7 or 8 articulated and divided rays. 
The anal fin is relatively very small, apparently with 8 or 
9 rays, but imperfectly preserved. The caudal fin is also 
imperfect, but distinctly forked. Where the scales are 
partially broken away, their posterior serrations are 
especially well seen upon the pale-coloured matrix.
